I've got the Integy Super Duty bulks and they're great. I know they probably weight a little more than the stock ones or even some of the other aluminum ones, but to me the strength is worth it. The bulks take a lot of punishment and I didn't want to have a weak link there.
the proline servo saver is pretty good. i think you have to make a little modification to the stock chassis. i would recommend just getting a heavy duty kimbrough servo saver and a bluebird 630mg. thats exactly what i have and im very happy with it.
Don't go the cheap route man you will just end up spending twice as much before you get some nice parts. Go UE off the start. I know you can't order over the internet, so i guess you are stuck with the lower quality stuff for now. MIP is second to UE so get MIP cvds. When I first started upgrading my maxx I broke arms and bulks left and right well to say the least i upgraded with integy and had some problems. Try your best to go for the good parts from the start and you won't regret it. I don't know how much you bash or beat on your truck but for me daily driving with integy always had disasters. Integy is super duty bulkheads are actually weaker than the stock traxxas shock towers or atleast thats what I found out when i broke the shock tower mounts on the bulk and not the shock tower.
hey braaaap
but when i went to the towerhobbies site it says on the comment thing
"COMMENTS: The CVD takes the place of the original half shafts.
This Will Not Work with the E-Maxx because it uses 6mm output
shafts and the T-Maxx uses 5mm output shafts."
